The processor can receive from the mobile device a first selection of a target device from the first list of computing devices and a second selection of an application from the second list of applications that is executable by the target device. The processor can facilitate the virtual private network session between the target device and a service node providing services to the target device via the virtual private network session. The services provided to the target device by the service node can be limited to the application selected from the second list of applications.

One embodiment of the subject disclosure includes a non-transitory computer-readable storage device comprising instructions which, responsive to being executed by a processor, cause the processor to perform operations including receiving from a first device a request to enable facilitation of a virtual private network session on behalf of devices other than the first device, and receiving from the first device authentication information to validate the request. The processor can perform additional operations responsive to successfully authenticating the first device, including transmitting to the first device a first list of computing devices and receiving from the first device a first selection of a target device from the first list of computing devices. The processor can facilitate the virtual private network session between the target device and a service node providing services to the target device via the virtual private network session.

One embodiment of the subject disclosure is a method including transmitting, by a controller comprising a processor, a request to a server to enable initiation of a virtual private network session on behalf of devices other than the controller. The method can include transmitting, by the controller, authentication information to enable the server to validate the request. The method can include receiving, by the controller, from the server a first list of computing devices, and transmitting, by the controller, to the server a first selection of a target device from the first list of computing devices to cause the server to initiate the virtual private network session between the target device and a service node providing services to the target device via the virtual private network session.

FIG. 1 depicts an illustrative embodiment of a first communication system 100 for delivering media content. Communication system 100 includes computing devices that can be connected in a virtual private network. The communication system 100 can represent an Internet Protocol Television (IPTV) media system. Communication system 100 can be overlaid or operably coupled with systems 500 or 800 of FIGS. 5 and 8 respectively, as another representative embodiment of communication system 100. In particular, a computing device included in communication system 100 (for example, device 130) can function as a server receiving a request from a mobile communication device to establish a connection with a virtual private network client on another device remote from the server, receiving an encrypted data stream from the mobile communication device, performing a two-factor authentication process to authenticate the mobile communication device, transmitting to the mobile communication device a first list of remote devices authorized to execute the virtual private network client and a second list of applications executable on a remote device included in the first list, receiving from the mobile communication device a first selection of a target device from the first list and a second selection of an application from the second list, establishing the connection with the target device, enabling the target device to execute the virtual private network client to initiate a virtual private network session, and enabling the target device to execute the selected application in the virtual private network session.

The IPTV media system can include a super head-end office (SHO) 110 with at least one super headend office server (SHS) 111 which receives media content from satellite and/or terrestrial communication systems. In the present context, media content can represent, for example, audio content, moving image content such as 2D or 3D videos, video games, virtual reality content, still image content, and combinations thereof. The SHS server 111 can forward packets associated with the media content to one or more video head-end servers (VHS) 114 via a network of video head-end offices (VHO) 112 according to a multicast communication protocol.

The VHS 114 can distribute multimedia broadcast content via an access network 118 to commercial and/or residential buildings 102 housing a gateway 104 (such as a residential or commercial gateway). The access network 118 can represent a group of digital subscriber line access multiplexers (DSLAMs) located in a central office or a service area interface that provide broadband services over fiber optical links or copper twisted pairs 119 to buildings 102. The gateway 104 can use communication technology to distribute broadcast signals to media processors 106 such as Set-Top Boxes (STBs) which in turn present broadcast channels to media devices 108 such as computers or television sets managed in some instances by a media controller 107 (such as an infrared or RF remote controller).

The gateway 104, the media processors 106, and media devices 108 can utilize tethered communication technologies (such as coaxial, powerline or phone line wiring) or can operate over a wireless access protocol such as Wireless Fidelity (WiFi), Bluetooth, Zigbee, or other present or next generation local or personal area wireless network technologies. By way of these interfaces, unicast communications can also be invoked between the media processors 106 and subsystems of the IPTV media system for services such as video-on-demand (VoD), browsing an electronic programming guide (EPG), or other infrastructure services.

A satellite broadcast television system 129 can be used in the media system of FIG. 1. The satellite broadcast television system can be overlaid, operably coupled with, or replace the IPTV system as another representative embodiment of communication system 100. In this embodiment, signals transmitted by a satellite 115 that include media content can be received by a satellite dish receiver 131 coupled to the building 102. Modulated signals received by the satellite dish receiver 131 can be transferred to the media processors 106 for demodulating, decoding, encoding, and/or distributing broadcast channels to the media devices 108. The media processors 106 can be equipped with a broadband port to an Internet Service Provider (ISP) network 132 to enable interactive services such as VoD and EPG as described above.

In yet another embodiment, an analog or digital cable broadcast distribution system such as cable TV system 133 can be overlaid, operably coupled with, or replace the IPTV system and/or the satellite TV system as another representative embodiment of communication system 100. In this embodiment, the cable TV system 133 can also provide Internet, telephony, and interactive media services.

The subject disclosure can apply to other present or next generation over-the-air and/or landline media content services system.

Some of the network elements of the IPTV media system can be coupled to one or more computing devices 130, a portion of which can operate as a web server for providing web portal services over the ISP network 132 to wireline media devices 108 or wireless communication devices 116. In addition, device 130 can operate as a virtual private network (VPN) provisioning and maintenance server for providing VPN services, as described in more detail below.

Communication system 100 can also provide for all or a portion of the computing devices 130 to function as a virtual private network platform server (herein referred to as a platform). The platform can use computing and communication technology to initiate VPN connections, which can include among other things, receiving and authenticating connection requests. In particular, the wireless communication devices 116 can be provisioned with secure messaging and encryption functions to utilize the services of the platform.

Multiple forms of media services can be offered to media devices over landline technologies such as those described above. Additionally, media services can be offered to media devices by way of a wireless access base station 117 operating according to common wireless access protocols such as Global System for Mobile or GSM, Code Division Multiple Access or CDMA, Time Division Multiple Access or TDMA, Universal Mobile Telecommunications or UMTS, World interoperability for Microwave or WiMAX, Software Defined Radio or SDR, Long Term Evolution or LTE, and so on. Other present and next generation wide area wireless access network technologies can be used in one or more embodiments of the subject disclosure.

FIG. 2 depicts an illustrative embodiment of a communication system 200 employing an IP Multimedia Subsystem (IMS) network architecture to facilitate the combined services of circuit-switched and packet-switched systems. Communication system 200 can be overlaid or operably coupled with system 500 or system 800 (shown in FIGS. 5 and 8 respectively) and communication system 100 as another representative embodiment of communication system 100. Furthermore, system 200 can include an application server performing a method a method including receiving, by the server, a request from a mobile communication device to establish a connection with a virtual private network client on a remote device; receiving, by the server, an encrypted data stream from the mobile communication device including an identifier for the mobile communication device; performing, by the server, a multi-factor authentication process to authenticate the mobile communication device; transmitting by the server to the mobile communication device a first list of remote devices authorized to execute the virtual private network client; receiving, by the server, from the mobile communication device a first selection of a target device from the first list; establishing, by the server, the connection with the target device; and enabling, by the server, the target device to execute the virtual private network client, thereby initiating a virtual private network session.

Communication system 200 can comprise a Home Subscriber Server (HSS) 240, a tElephone NUmber Mapping (ENUM) server 230, and other network elements of an IMS network 250. The IMS network 250 can establish communications between IMS-compliant communication devices (CDs) 201, 202, Public Switched Telephone Network (PSTN) CDs 203, 205, and combinations thereof by way of a Media Gateway Control Function (MGCF) 220 coupled to a PSTN network 260. The MGCF 220 need not be used when a communication session involves IMS CD to IMS CD communications. A communication session involving at least one PSTN CD may utilize the MGCF 220.

IMS CDs 201, 202 can register with the IMS network 250 by contacting a Proxy Call Session Control Function (P-CSCF) which communicates with an interrogating CSCF (I-CSCF), which in turn, communicates with a Serving CSCF (S-CSCF) to register the CDs with the HSS 240. To initiate a communication session between CDs, an originating IMS CD 201 can submit a Session Initiation Protocol (SIP INVITE) message to an originating P-CSCF 204 which communicates with a corresponding originating S-CSCF 206. The originating S-CSCF 206 can submit the SIP INVITE message to one or more application servers (aSs) 217 that can provide a variety of services to IMS subscribers.

For example, the application servers 217 can be used to perform originating call feature treatment functions on the calling party number received by the originating S-CSCF 206 in the SIP INVITE message. Originating treatment functions can include determining whether the calling party number has international calling services, call ID blocking, calling name blocking, 7-digit dialing, and/or is requesting special telephony features (e.g., *72 forward calls, *73 cancel call forwarding, *67 for caller ID blocking, and so on). Based on initial filter criteria (iFCs) in a subscriber profile associated with a CD, one or more application servers may be invoked to provide various call originating feature services.

Additionally, the originating S-CSCF 206 can submit queries to the ENUM system 230 to translate an E.164 telephone number in the SIP INVITE message to a SIP Uniform Resource Identifier (URI) if the terminating communication device is IMS-compliant. The SIP URI can be used by an Interrogating CSCF (I-CSCF) 207 to submit a query to the HSS 240 to identify a terminating S-CSCF 214 associated with a terminating IMS CD such as reference 202. Once identified, the I-CSCF 207 can submit the SIP INVITE message to the terminating S-CSCF 214. The terminating S-CSCF 214 can then identify a terminating P-CSCF 216 associated with the terminating CD 202. The P-CSCF 216 may then signal the CD 202 to establish Voice over Internet Protocol (VoIP) communication services, thereby enabling the calling and called parties to engage in voice and/or data communications. Based on the iFCs in the subscriber profile, one or more application servers may be invoked to provide various call terminating feature services, such as call forwarding, do not disturb, music tones, simultaneous ringing, sequential ringing, etc.

In some instances the aforementioned communication process is symmetrical. Accordingly, the terms “originating” and “terminating” in FIG. 2 may be interchangeable. It is further noted that communication system 200 can be adapted to support video conferencing. In addition, communication system 200 can be adapted to provide the IMS CDs 201, 202 with the multimedia and Internet services of communication system 100 of FIG. 1.

If the terminating communication device is instead a PSTN CD such as CD 203 or CD 205 (in instances where the cellular phone only supports circuit-switched voice communications), the ENUM system 230 can respond with an unsuccessful address resolution which can cause the originating S-CSCF 206 to forward the call to the MGCF 220 via a Breakout Gateway Control Function (BGCF) 219. The MGCF 220 can then initiate the call to the terminating PSTN CD over the PSTN network 260 to enable the calling and called parties to engage in voice and/or data communications.

It is further appreciated that the CDs of FIG. 2 can operate as wireline or wireless devices. For example, the CDs of FIG. 2 can be communicatively coupled to a cellular base station 221, a femtocell, a WiFi router, a Digital Enhanced Cordless Telecommunications (DECT) base unit, or another suitable wireless access unit to establish communications with the IMS network 250 of FIG. 2. The cellular access base station 221 can operate according to common wireless access protocols such as GSM, CDMA, TDMA, UMTS, WiMax, SDR, LTE, and so on. Other present and next generation wireless network technologies can be used by one or more embodiments of the subject disclosure. Accordingly, multiple wireline and wireless communication technologies can be used by the CDs of FIG. 2.

Cellular phones supporting LTE can support packet-switched voice and packet-switched data communications and thus may operate as IMS-compliant mobile devices. In this embodiment, the cellular base station 221 may communicate directly with the IMS network 250 as shown by the arrow connecting the cellular base station 221 and the P-CSCF 216.

Alternative forms of a CSCF can operate in a device, system, component, or other form of centralized or distributed hardware and/or software. Indeed, a respective CSCF may be embodied as a respective CSCF system having one or more computers or servers, either centralized or distributed, where each computer or server may be configured to perform or provide, in whole or in part, any method, step, or functionality described herein in accordance with a respective CSCF. Likewise, other functions, servers and computers described herein, including but not limited to, the HSS, the ENUM server, the BGCF, and the MGCF, can be embodied in a respective system having one or more computers or servers, either centralized or distributed, where each computer or server may be configured to perform or provide, in whole or in part, any method, step, or functionality described herein in accordance with a respective function, server, or computer.

The server 130 of FIG. 1 can be operably coupled to communication system 200 for purposes similar to those described above. Server 130 can perform VPN platform functions and provide VPN services to the CDs 201, 202, 203 and 205 of FIG. 2. CDs 201, 202, 203 and 205, which can be adapted with software to execute the mobile app to request that a VPN session be established using the VPN platform. The VPN platform can be an integral part of the application servers 217 performing authentication of mobile devices, which can be adapted to the operations of the IMS network 250.

For illustration purposes only, the terms S-CSCF, P-CSCF, I-CSCF, and so on, can be server devices, but may be referred to in the subject disclosure without the word “server.” It is also understood that any form of a CSCF server can operate in a device, system, component, or other form of centralized or distributed hardware and software. It is further noted that these terms and other terms such as DIAMETER commands are terms can include features, methodologies, and/or fields that may be described in whole or in part by standards bodies such as 3^(rd) Generation Partnership Project (3GPP). It is further noted that some or all embodiments of the subject disclosure may in whole or in part modify, supplement, or otherwise supersede final or proposed standards published and promulgated by 3GPP.

FIG. 3 depicts an illustrative embodiment of a web portal 302 which can be hosted by server applications operating from the computing devices 130 of the communication system 100 illustrated in FIG. 1. Communication system 300 can be communicatively coupled to systems 500 and 800 of FIGS. 5 and 8, communication system 100, and/or communication system 200. The web portal 302 can be used for managing services of systems 500 and 800 of FIGS. 5 and 8 and communication systems 100, 200. A web page of the web portal 302 can be accessed by a Uniform Resource Locator (URL) with an Internet browser using an Internet-capable communication device such as those described in FIGS. 1 and 2. The web portal 302 can be configured, for example, to access a media processor 106 and services managed thereby such as a Digital Video Recorder (DVR), a Video on Demand (VoD) catalog, an Electronic Programming Guide (EPG), or a personal catalog (such as personal videos, pictures, audio recordings, etc.) stored at the media processor 106. The web portal 302 can also be used for provisioning IMS services described earlier, provisioning Internet services, provisioning cellular phone services, and so on.

The web portal 302 can further be utilized to manage and provision virtual private network services as may be desired by subscribers and/or service providers of systems 200, 400, 500 and 800.

FIG. 4 depicts an illustrative embodiment of a communication device 400. Communication device 400 can serve in whole or in part as an illustrative embodiment of the devices depicted in FIGS. 1 and 2. Communication device 400 in whole or in part can represent any of the mobile devices described in FIGS. 5 and 8, and can be configured to perform portions of the methods of FIGS. 6, 7 and 9.

Communication device 400 can comprise a wireline and/or wireless transceiver 402 (herein transceiver 402), a user interface (UI) 404, a power supply 414, a location receiver 416, a motion sensor 418, an orientation sensor 420, and a controller 406 for managing operations thereof. The transceiver 402 can support short-range or long-range wireless access technologies such as Bluetooth, ZigBee, WiFi, DECT, or cellular communication technologies, just to mention a few. Cellular technologies can include, for example, CDMA-1X, UMTS/HSDPA, GSM/GPRS, TDMA/EDGE, EV/DO, WiMAX, SDR, LTE, as well as other next generation wireless communication technologies as they arise. The transceiver 402 can also be adapted to support circuit-switched wireline access technologies (such as PSTN), packet-switched wireline access technologies (such as TCP/IP, VoIP, etc.), and combinations thereof.

The UI 404 can include a depressible or touch-sensitive keypad 408 with a navigation mechanism such as a roller ball, a joystick, a mouse, or a navigation disk for manipulating operations of the communication device 400. The keypad 408 can be an integral part of a housing assembly of the communication device 400 or an independent device operably coupled thereto by a tethered wireline interface (such as a USB cable) or a wireless interface supporting for example Bluetooth. The keypad 408 can represent a numeric keypad commonly used by phones, and/or a QWERTY keypad with alphanumeric keys. The UI 404 can further include a display 410 such as monochrome or color LCD (Liquid Crystal Display), OLED (Organic Light Emitting Diode) or other suitable display technology for conveying images to an end user of the communication device 400. In an embodiment where the display 410 is touch-sensitive, a portion or all of the keypad 408 can be presented by way of the display 410 with navigation features.

The display 410 can use touch screen technology to also serve as a user interface for detecting user input. As a touch screen display, the communication device 400 can be adapted to present a user interface with graphical user interface (GUI) elements that can be selected by a user with a touch of a finger. The touch screen display 410 can be equipped with capacitive, resistive or other forms of sensing technology to detect how much surface area of a user's finger has been placed on a portion of the touch screen display. This sensing information can be used to control the manipulation of the GUI elements or other functions of the user interface. The display 410 can be an integral part of the housing assembly of the communication device 400 or an independent device communicatively coupled thereto by a tethered wireline interface (such as a cable) or a wireless interface.

The UI 404 can also include an audio system 412 that utilizes audio technology for conveying low volume audio (such as audio heard in proximity of a human ear) and high volume audio (such as speakerphone for hands free operation). The audio system 412 can further include a microphone for receiving audible signals of an end user. The audio system 412 can also be used for voice recognition applications. The UI 404 can further include an image sensor 413 such as a charged coupled device (CCD) camera for capturing still or moving images.

The power supply 414 can utilize common power management technologies such as replaceable and rechargeable batteries, supply regulation technologies, and/or charging system technologies for supplying energy to the components of the communication device 400 to facilitate long-range or short-range portable applications. Alternatively, or in combination, the charging system can utilize external power sources such as DC power supplied over a physical interface such as a USB port or other suitable tethering technologies.

The location receiver 416 can utilize location technology such as a global positioning system (GPS) receiver capable of assisted GPS for identifying a location of the communication device 400 based on signals generated by a constellation of GPS satellites, which can be used for facilitating location services such as navigation. The motion sensor 418 can utilize motion sensing technology such as an accelerometer, a gyroscope, or other suitable motion sensing technology to detect motion of the communication device 400 in three-dimensional space. The orientation sensor 420 can utilize orientation sensing technology such as a magnetometer to detect the orientation of the communication device 400 (north, south, west, and east, as well as combined orientations in degrees, minutes, or other suitable orientation metrics).

The communication device 400 can use the transceiver 402 to also determine a proximity to a cellular, WiFi, Bluetooth, or other wireless access points by sensing techniques such as utilizing a received signal strength indicator (RSSI) and/or signal time of arrival (TOA) or time of flight (TOF) measurements. The controller 406 can utilize computing technologies such as a microprocessor, a digital signal processor (DSP), programmable gate arrays, application specific integrated circuits, and/or a video processor with associated storage memory such as Flash, ROM, RAM, SRAM, DRAM or other storage technologies for executing computer instructions, controlling, and processing data supplied by the aforementioned components of the communication device 100.

The reset button can be used to reset the controller 406 of the communication device 400. In yet another embodiment, the communication device 400 can also include a factory default setting button positioned, for example, below a small hole in a housing assembly of the communication device 400 to force the communication device 400 to re-establish factory settings. In this embodiment, a user can use a protruding object such as a pen or paper clip tip to reach into the hole and depress the default setting button. The communication device 400 can also include a slot for adding or removing an identity module such as a Subscriber Identity Module (SIM) card. SIM cards can be used for identifying subscriber services, executing programs, storing subscriber data, and so forth.

The communication device 400 as described herein can operate with more or fewer of the circuit components shown in FIG. 4. These variant embodiments can be used in one or more embodiments of the subject disclosure.

The communication device 400 can be adapted to perform the functions of the media processor 106, the media devices 108, or the portable communication devices 116 of FIG. 1, as well as the IMS CDs 201-202 and PSTN CDs 203-205 of FIG. 2. It will be appreciated that the communication device 400 can also represent other devices that can operate in communication systems 100, 200 of FIGS. 1 and 2 such as a gaming console and a media player.

The communication device 400 shown in FIG. 4 or portions thereof can serve as a representation of one or more of the devices of communication system 100 and communication system 200. In addition, the controller 406 can be adapted in various embodiments to execute a mobile application (mobile app) 460 to manage connections in a virtual private network.

According to the disclosure, a virtual private network (VPN) can be established by a simple and secure process where a mobile device initiates a VPN connection to another device; the other device can be a laptop, desktop, tablet, server, etc. In embodiments of the disclosure, VPN connections are made more secure by eliminating inward access to an enterprise; all connectivity is initiated from a central VPN server going outward. In other embodiments, devices can be deployed that allow connectivity to external networks.

In accordance with an embodiment of the disclosure, a virtual private network can be established as schematically illustrated in FIG. 5. In this embodiment, a mobile app for enabling a VPN session in system 500 executes on a mobile device (e.g. a cell phone) 501. The mobile app communicates with a VPN platform 551 hosted on a server operating in a network, schematically shown as cloud 550. Platform 551 connects to an authorized client device 560. As shown in FIG. 5, provisioning and maintenance of the VPN service may be performed on a separate server 552, communicating with the VPN platform via a communication link 553. The mobile app can request a VPN connection on behalf of the client device. When a VPN connection is desired, the mobile app sends a secure request to the platform, which then pushes the VPN connection to the client device.

The mobile app is provisioned on device 501 by a service provider (e.g. a provider of network services on system 100). In this embodiment, the mobile device user's VPN credentials, including an identifier 511 for the device and a user PIN 512, are stored at the device. The mobile app sends a secure request 521 to the platform 551, which authenticates the mobile app and transmits an encrypted data stream 522 with a list 513 of devices authorized to establish a VPN connection with the platform. A secure message 523 identifying the selected device (e.g. laptop 560) is transmitted to the platform. The VPN platform 551 then initiates a connection to the authorized device in accordance with device polling, as detailed below. In an embodiment, the platform facilitates a VPN session between device 560 and a service node providing services to device 560. The service node may be integral to the server hosting platform 551, or alternatively may be a virtual machine executing on the server. In another embodiment, the service node can be remotely located from the server hosting platform 551 such as illustrated by server 841 (see FIG. 8).

FIG. 6 is a flowchart showing steps in a procedure 600 for establishing a virtual private network, in accordance with an embodiment of the disclosure. Procedure 600 can be advantageously performed using system 500. An application executing on mobile device 501 (mobile app) serves as an interface between a user of mobile device 501 and the VPN platform 551. The user first configures the mobile app on device 501 if this has not already been done (step 602). The mobile app is configured with the user's VPN credentials, which are saved within the app (step 604). In this embodiment, the credentials include identification of the VPN infrastructure to be used, the user's VPN identifier, and the user's PIN. The credentials are stored at a secure storage device on device 501.

In an embodiment, the user follows a login procedure for the mobile app which can include a multi-factor authentication process. The mobile app can include a seed for multi-factor authentication obtained from the service provider. In this embodiment, two-factor authentication is used, and the seed is a hash based on a pre-determined value configured when the user is provisioned for the service. For example, the user can select a secret phrase that is encrypted on both the mobile device 501 and the VPN platform 551. The two-factor authentication is enabled (step 606) by hashing the combined values of user ID 511 and PIN 512 with DATE and TIME.

When the user indicates via the mobile device 501 that a VPN connection is desired, the mobile app prompts the user for the PIN 512 (step 608). The mobile app then transmits a request 521 to the platform 551 (step 610). The request 521 can be via IP, SMS, or a phone call (generally, any means for transmitting data from device 501 to platform 551). The platform 551 initiates an authentication process (step 612), in which data is sent from the mobile app to the VPN platform via an encrypted stream.

The VPN platform maintains a list of devices that are authorized to execute a VPN client (that is, devices that have provided authentication information to the platform and are trusted by the platform). If the authentication is successful (step 614), this list of devices is sent to the mobile app (step 616) and displayed to the user as a list of selectable items 513 on device 501 (step 618). The mobile app can receive this information via IP, SMS or some other convenient means. The user selects a device from the list displayed on the mobile app (step 620). This selection is sent in an encrypted data stream 523 to the VPN platform (step 622). The encrypted stream 523 can be sent via IP, SMS or some other means as mentioned above. Data stream 523 also includes information to ensure that the user selection is an authorized transaction. The authorized device (in this embodiment, laptop 560) is configured with a VPN client; the VPN client polls the VPN platform (step 624) to determine if a VPN connection is pending. The VPN platform 551 then initiates a connection to the authorized device (step 626) in accordance with the device polling, as detailed below. As shown in FIG. 5, devices 501 and 560 communicate separately with platform 551 and are not communicatively coupled to each other. In an embodiment, however, both devices may be located conveniently to the user, who can perform the login procedure using mobile device 501 but then work with an application loaded on laptop 560. Since device 560 is authorized to execute a VPN client and is trusted by the platform, another login from device 560 is not required.

The authorized device 560 (selected by the user of the mobile device 501) that uses the VPN connection is configured with a VPN client that polls the VPN platform to determine if a VPN connection is pending. FIG. 7 is a flowchart showing additional steps in a procedure 700 for establishing a virtual private network, in accordance with an embodiment of the disclosure. As part of the VPN service provisioning process, the VPN platform shares authentication information with the VPN client. In an embodiment, the VPN client can be configured with a device certificate (step 702) in a public-key infrastructure (PKI) arrangement. The VPN client polls the platform (step 704) at a preset interval (e.g. every 60 seconds). In an embodiment, the VPN client is implemented on the authorized device 560 so that the device displays an icon 561 indicating the status of the connection. In another embodiment, the display also includes a “Poll Now” button 563 so that a user of device 560 can initiate polling before the next poll interval (step 705).

If a VPN connection request is pending (step 706), the platform answers the poll from the VPN client at the authorized device by signaling the client that a connection is ready (step 708). The VPN client then establishes a tunnel 554 to the VPN platform (step 710) so that a VPN session can be initiated by the platform at the authorized device (step 712). The device display is updated (step 714) to indicate that a VPN connection to the device has been established.

FIG. 8 schematically illustrates a system 800, in accordance with another embodiment of the disclosure, in which a VPN connection is requested using a mobile app on behalf of an authorized device 860, so that an application executes on that other device. As described above with reference to FIG. 5, a mobile app executing on device 501 sends a secure message 821 to platform 551 which authenticates the mobile app and transmits an encrypted data stream 822 to device 501. The data stream 822 includes a list of devices authorized to establish a VPN connection with the platform, and also includes a list 813 of applications that can be executed on the selected device in a VPN session. (As noted above, the listed devices may be located conveniently to device 501, but are not communicatively coupled to device 501 or to each other.) Although the user logs in (provides his PIN) via device 501, the VPN session is initiated on device 860 and the selected application may be used on device 860 without a further login. In the example shown in FIG. 8, the user of device 501 selects a tablet device, on which email and banking applications can be executed. (Device 860 may be capable of executing various other applications, but the VPN session in this embodiment is limited to the specific application selected by the user.) If the user selects a banking application for the tablet device, a secure message 823 identifying the selected device (tablet 860) and the selected application (banking application 840) is transmitted to the platform. The VPN platform 551 then initiates a VPN connection to the tablet, and also causes the authorized device 860 to execute the banking application 840. In an embodiment, the VPN client is configured so that the VPN session is limited to the application selected by the user (in this example, banking app 840).

In an embodiment, the authorized device 860 is itself connected to another network 870, and remains connected to network 870 while executing the selected application in the VPN session. In this instance, device 860 can be viewed as having a compartmented VPN, on which the banking application is executed in a virtual machine (VM) session.

In a further embodiment, the selected application (in this example, banking application 840) is not configured on the authorized device (in this example, tablet 860) before initiation of the VPN session by platform 551. Platform 551 then establishes the VPN connection to the authorized device, retrieves the selected application from a server 841 via a communication path 842, and distributes the application to the authorized device. In a particular embodiment, platform 551 distributes the application on the fly, as part of the VPN session initiation process. A VPN session is thereby facilitated in which a secure banking or other service is performed, where a VPN is enabled, and where a trusted app is delivered to be used. In the course of executing the banking app in the VPN session, device 860 may communicate with server 841, but only through VPN platform 551. Server 841 is shown in FIG. 8 as remote from platform 551, but alternatively may be integrated with platform 551 or comprise a virtual machine executing alongside platform 551 on the same computing device. In an embodiment, server 841 functions as a service node providing services to device 860 via the virtual private network session. In another embodiment, a first virtual private network session is facilitated between platform 551 and the service node (such as server 841), a second virtual private network session is facilitated between platform 551 and device 860, and a connection is facilitated between the first virtual private network session and the second virtual private network session. Device 860, on whose behalf the mobile app on device 501 requested the VPN session, communicates with platform 551 via path 554 but is not communicatively coupled with device 501 or service node 841 (even though the service node may be a virtual machine executing on the same device as platform 551). Service node 841 communicates with platform 551 via path 842 but is not communicatively coupled with device 501 or device 860.

FIG. 9 is a flowchart showing steps in a procedure 900 for establishing a virtual private network in which a selected application is executed, in accordance with an embodiment of the disclosure. Procedure 900 can be advantageously performed using system 800. A mobile application offering multi-factor authentication serves as an interface between a user of mobile device 501 and the VPN platform 550. The user first configures the mobile app on device 501 if this has not already been done (step 902). The mobile app is configured with the user's VPN credentials, which are saved within the app (step 904). In this embodiment, the credentials include identification of the VPN infrastructure to be used, the user's VPN identifier, and the user's PIN. The credentials are stored at a secure storage device on device 501.

The mobile app also includes a seed for multi-factor authentication obtained from the service provider. In this embodiment, two-factor authentication is used, and the seed is a hash based on a pre-determined value configured when the user is provisioned for the service. For example, the user can select a secret phrase that is encrypted on both the mobile device 501 and the VPN platform 551. The two-factor authentication is enabled (step 906) by hashing the combined values of user ID 511 and PIN 512 with DATE and TIME.

When the user indicates via the mobile device 501 that a VPN connection is desired, the mobile app prompts the user for the PIN 512 (step 908). The mobile app then transmits a request 821 to the platform 551 (step 910). The request 821 can be via IP, SMS, or a phone call (generally, any means for transmitting data from device 501 to platform 551). The platform 551 initiates an authentication process (step 912), in which data is sent from the mobile app to the VPN platform via an encrypted stream.

The VPN platform maintains a list of devices that are authorized to execute a VPN client, and a list of applications that can run on a selected device with a compartmented VPN. If the authentication is successful (step 914), the list of devices and associated applications is sent to the mobile app (step 916) and displayed to the user as a list of selectable items 813 on device 501 (step 918). The mobile app can receive this information via IP, SMS or some other convenient means. The user selects a device from the list displayed on the mobile app (step 920). This selection is sent in an encrypted data stream 823 to the VPN platform (step 922). The encrypted stream 823 can be sent via IP, SMS or some other means as mentioned above. Data stream 823 also includes information to ensure that the user selection is an authorized transaction. The authorized device (in this embodiment, tablet 860 remote from mobile device 501) is configured with a VPN client; the VPN client polls the VPN platform (step 924) to determine if a VPN connection is pending. The VPN platform 551 then initiates a connection to the authorized device in accordance with the device polling (step 926).

The VPN platform can initiate a VPN connection to the authorized device (which is configured with a VPN client and device certificate) according to procedure 700. If the selected application is already loaded on the authorized device (step 928), the VPN client proceeds to execute the application (step 932). Otherwise, the VPN platform retrieves the application and delivers the application to the VPN client (step 930).

As noted above, software solutions for banking and finance can be implemented according to embodiments of the disclosure, where connectivity is initiated by a trusted device (mobile application) that then initiates a secure VPN from a VPN server farm to authorized devices. In particular, solutions for banking and finance can be implemented where a trusted device initiates the connection in potentially an out of band manner and whereby the VPN platform initiates the connection, eliminating inbound access to the VPN. In other embodiments, applications can be executed on the fly whereby the mobile application lists specific applications that can be initiated on authorized devices. A system implementing this solution can enable not only VPN connectivity, but also distribute and execute remote applications in a secure manner.

According to the disclosure, applications can be enabled to run remotely at authorized devices after a VPN session is initiated. It will be appreciated that applications can be delivered inline to a virtual machine to provide improved security, since not only the VPN but also the application running remotely would be executed on an authorized device.

Upon reviewing the aforementioned embodiments, it would be evident to an artisan with ordinary skill in the art that said embodiments can be modified, reduced, or enhanced without departing from the scope of the claims described below. For example, the functions of the above-described mobile device could be performed by a stationary device executing an application to enable facilitation of a VPN session on behalf of another device. Other embodiments can be used in the subject disclosure.
